SECURE DATA SHARING IN CLOUD ENVIRONMENT USING CRYPTOGRAPHY

Abstract

Cloud computing [i] architecture provides the services for client’s on-demand. It made users not to hold on any hardware requirements and complexities for maintenance. The widespread problem associated with cloud computing is data privacy. Existing system has attribute based encryption (ABE) which assigns keys for each registered clients, but the computational cost is very high and the other model is tree based key management that is designed for secure and flexible key management. In this model there is leakage for key generation and distribution. So we propose a system which uses quantum key distribute on and advance encryption standard for the users to provide confidentiality by hiding all the useful information while transferring data.
